How to Print PDF in VB.NET Without Adobe Using IronPrint

How Do You Install IronPrint in a VB.NET Project?

Installing IronPrint takes seconds through the NuGet Package Manager. Open your Package Manager Console in Visual Studio and run:

Install-Package IronPrint

After installation, add the namespace import at the top of any file that needs printing, then apply your license key before calling any IronPrint method:

Imports IronPrint

' Apply your license key (get a free trial key at ironsoftware.com)
License.LicenseKey = "YOUR-LICENSE-KEY"

Imports IronPrint

' Apply your license key (get a free trial key at ironsoftware.com)
License.LicenseKey = "YOUR-LICENSE-KEY"

IronPrint targets .NET Framework 4.6.2 and above, as well as .NET 6, 7, 8, 9, and 10. It ships with native rendering engines for each platform, so you do not need to install Adobe Acrobat, Ghostscript, or any other PDF renderer. The same NuGet package works for Windows Forms, WPF, console applications, and ASP.NET projects written in VB.NET.

Supported document formats include PDF, PNG, HTML, TIFF, GIF, JPEG, and BMP. You can explore the full capabilities in the IronPrint unified printing API reference.

How Do You Print a PDF Silently in VB.NET?

Silent printing sends a document directly to a printer without showing any dialog boxes. This mode is essential for automated workflows, batch invoice processing, report generation pipelines, and server-side document printing where no user is present.

According to Microsoft's documentation on GDI+ printing in .NET, traditional .NET printing involves creating a PrintDocument object, hooking into PrintPage events, and manually handling page layout. IronPrint eliminates all of that boilerplate:

Imports IronPrint

Module SilentPrinting
    Sub Main()
        Dim pdfPath As String = "invoice.pdf"

        ' Print to the system default printer
        Printer.Print(pdfPath)

        ' Print to a specific printer by name
        Dim settings As New PrintSettings()
        settings.PrinterName = "Microsoft Print to PDF"
        Printer.Print(pdfPath, settings)
    End Sub
End Module

Imports IronPrint

Module SilentPrinting
    Sub Main()
        Dim pdfPath As String = "invoice.pdf"

        ' Print to the system default printer
        Printer.Print(pdfPath)

        ' Print to a specific printer by name
        Dim settings As New PrintSettings()
        settings.PrinterName = "Microsoft Print to PDF"
        Printer.Print(pdfPath, settings)
    End Sub
End Module

The Printer.Print method handles all the PDF rendering internally. When you call Printer.Print(pdfPath) without a PrintSettings argument, IronPrint selects the system default printer automatically. When you supply a PrintSettings object with a PrinterName value, it routes the job to that specific device.

For batch scenarios, you can loop over a list of file paths and call Printer.Print for each one. Because IronPrint does not open any UI thread for silent printing, it works correctly in console applications, Windows services, and ASP.NET request handlers.

For a deeper look at the available options, read the IronPrint print settings documentation.

How Do You Show the Print Dialog Before Printing?

Sometimes you need to let users choose a printer, adjust the page range, or set the number of copies before committing to a print job. IronPrint provides Printer.ShowPrintDialog for exactly this scenario:

Imports IronPrint

Module DialogPrinting
    Sub Main()
        ' Display the standard Windows print dialog
        Printer.ShowPrintDialog("report.pdf")
    End Sub
End Module

Imports IronPrint

Module DialogPrinting
    Sub Main()
        ' Display the standard Windows print dialog
        Printer.ShowPrintDialog("report.pdf")
    End Sub
End Module

When this method runs, Windows displays its standard print dialog. The user can select any installed printer, pick a page range, choose the number of copies, and adjust duplex settings. After the user clicks Print or Cancel, control returns to your code.

This method integrates naturally into Windows Forms applications. You can call it from a button click handler and trust that the dialog will behave consistently with other Windows applications the user already knows.

The print dialog examples page shows additional use cases, including pre-selecting a printer or pre-populating the number of copies before the dialog opens.

How Do You Customize PDF Print Settings in VB.NET?

The PrintSettings class gives you full programmatic control over every aspect of a print job. You can set DPI, paper size, orientation, number of copies, and the target printer -- all before the job reaches the print queue:

Imports IronPrint

Module CustomPrintSettings
    Sub Main()
        Dim settings As New PrintSettings() With {
            .Dpi = 300,
            .NumberOfCopies = 2,
            .PaperOrientation = PaperOrientation.Landscape,
            .PaperSize = PaperSize.A4,
            .PrinterName = "Office Printer"
        }

        Printer.Print("document.pdf", settings)
    End Sub
End Module

Imports IronPrint

Module CustomPrintSettings
    Sub Main()
        Dim settings As New PrintSettings() With {
            .Dpi = 300,
            .NumberOfCopies = 2,
            .PaperOrientation = PaperOrientation.Landscape,
            .PaperSize = PaperSize.A4,
            .PrinterName = "Office Printer"
        }

        Printer.Print("document.pdf", settings)
    End Sub
End Module

How Do You Enumerate and Select Printers Programmatically?

In enterprise environments, workstations often have access to dozens of network printers. IronPrint makes it straightforward to list all available printers and pick the right one at runtime:

Imports IronPrint

Module PrinterManagement
    Sub Main()
        ' Retrieve all available printers
        Dim printers As List(Of String) = Printer.GetPrinterNames()

        Console.WriteLine($"Found {printers.Count} printer(s):")
        For Each printerName As String In printers
            Console.WriteLine($"  - {printerName}")
        Next

        ' Print to the first available printer
        If printers.Count > 0 Then
            Dim settings As New PrintSettings()
            settings.PrinterName = printers(0)
            Printer.Print("document.pdf", settings)
        Else
            Console.WriteLine("No printers found. Check system configuration.")
        End If
    End Sub
End Module

Imports IronPrint

Module PrinterManagement
    Sub Main()
        ' Retrieve all available printers
        Dim printers As List(Of String) = Printer.GetPrinterNames()

        Console.WriteLine($"Found {printers.Count} printer(s):")
        For Each printerName As String In printers
            Console.WriteLine($"  - {printerName}")
        Next

        ' Print to the first available printer
        If printers.Count > 0 Then
            Dim settings As New PrintSettings()
            settings.PrinterName = printers(0)
            Printer.Print("document.pdf", settings)
        Else
            Console.WriteLine("No printers found. Check system configuration.")
        End If
    End Sub
End Module

Printer.GetPrinterNames() queries the Windows print subsystem and returns every printer the current user can access, including local USB printers, network printers, virtual printers like Microsoft Print to PDF, and any printer drivers installed through third-party software.

How Do You Handle Print Errors in VB.NET?

Production printing code must handle failures gracefully. File paths might be wrong, printers might be offline, or the user account might lack print permissions. Wrapping your print calls in structured exception handling prevents unhandled exceptions from crashing your application:

Imports IronPrint
Imports System.IO

Module ErrorHandling
    Sub Main()
        Dim filePath As String = "document.pdf"

        If Not File.Exists(filePath) Then
            Console.WriteLine("PDF file not found. Verify the path and try again.")
            Return
        End If

        Try
            Dim settings As New PrintSettings()
            settings.PrinterName = "Office Printer"
            Printer.Print(filePath, settings)
            Console.WriteLine("Print job sent successfully.")
        Catch ex As Exception
            Console.WriteLine($"Printing failed: {ex.Message}")
        End Try
    End Sub
End Module

Imports IronPrint
Imports System.IO

Module ErrorHandling
    Sub Main()
        Dim filePath As String = "document.pdf"

        If Not File.Exists(filePath) Then
            Console.WriteLine("PDF file not found. Verify the path and try again.")
            Return
        End If

        Try
            Dim settings As New PrintSettings()
            settings.PrinterName = "Office Printer"
            Printer.Print(filePath, settings)
            Console.WriteLine("Print job sent successfully.")
        Catch ex As Exception
            Console.WriteLine($"Printing failed: {ex.Message}")
        End Try
    End Sub
End Module

How Do You Combine PDF Generation and Printing in VB.NET?

A common workflow involves generating a PDF at runtime and then immediately printing it -- for example, creating an invoice from database records and sending it to the printer in one step. IronPDF handles PDF creation, and IronPrint handles the output:

How Do You Print Multiple Pages and Control Page Ranges?

When printing large documents, you may need to print only specific pages -- for example, pages 1 through 5 of a 50-page report. IronPrint's PrintSettings class supports page range configuration:
